The bridge was named after Lance Corporal Harold J. Dillard, a Vietnam veteran who died in combat in 1967. Dillard, who graduated Hackensack High School, was killed while serving in the Quang Tri province in South Vietnam.

The bridge, formerly known as the Court Street Bridge, was built in 1908 and spans the Hackensack River between Hackensack and Bogota. Most of the original structure has been replaced using $17.7 million in stimulus funds awarded to the state department of transportation in 2009. In total, the project cost nearly $20 million.

Following the rededication, the nearby New Jersey Naval Museum will be offering free tours of the USS Ling, a submarine used during World War II.

The ceremony starts at 11 a.m., but the bridge will reopen to the public at 4 p.m.
